Paul Griffiths – The Baldwin effect and genetic assimilation

Paul Griffiths: University of Queensland Department of PhilosophyMany evolutionary processes have been described in which a trait that initially develops in the members of a population as a result of some interaction with the environment comes to develop without that interaction in their descendants. Waddington’s genetic assimilation is importantly different from the rest of this […]

Hillard Kaplan – The human adaptive complex and the evolution of the 70 year lifespan

Hillard Kaplan: University of New Mexico Department of AnthropologyThis paper will present an overview of age-specific mortality rates among hunter-gatherers and forager-horticulturalists. It will also present new data on resource transfers and physical rates of aging among Tsimane forager-horticulturalists in Bolivia. It will be argued that the balance of costs and benefits of maintenance and […]

Caitlin O’Connell-Rodwell – The Importance of Communication and Culture to the African Elephant

Caitlin O'Connell-Rodwell: Stanford University Department of Otolaryngology, Head and Neck SurgeryThe structure of African elephant society is primarily matriarchal in nature, where dominant female elephants make decisions for the herd as a whole with regard to safety, movements, resource choices and affiliations. Culture is often influenced by local environmental and social pressures, as well as […]

Nicola S. Clayton – Memories of Tomorrow: Do Animals Remember the Past and Plan for the Future?

Nicola S. Clayton: University of Cambridge Department of Experimental PsychologyAccording to the mental time travel hypothesis only humans can mentally dissociate themselves from the present, travelling backwards in time to recollect specific past events about what happened where and when (episodic memory) and travelling forwards in time to anticipate future needs (future planning). Studies on […]

James Roney – Preliminary data testing an alternative explanation for menstrual phase effects on women’s mate preferences

James Roney: UC Santa Barbara Department of PsychologyMenstrual cycle shifts in women's mate preferences have generally been interpreted as products of adaptations designed to alter behavior during the fertile window relative to other times in the cycle. I will discuss an alternative theory that posits that such shifts may be produced by mechanisms designed to […]

Janet Sinsheimer – Family Feuds: Maternal-Fetal Genotype Incompatibility

Janet Sinsheimer: UCLA Departments of Human Genetics, Biomathematics and BiostatisticsBiological mechanisms involving a combination of genetic and environmental factors have been hypothesized to explain susceptibility to complex familial disease. I will present our efforts to detect interactions between mother's and child's genes that may create adverse prenatal environments and increase susceptibility to diseases such as […]

Carl Lipo – Resolution of the Cultural Phylogenies of Monumental Statues on Easter Island

Carl Lipo: CSU Long Beach Department of AnthropologyThe monumental statues (moai) of Easter Island represent substantial investment in cultural elaboration by the prehistoric islanders. Constructing explanations of these features requires generating measurements of temporal and spatial statue variability. Using a method based in cultural transmission, cladistics and occurrence seriation I present the results of analysis […]

Stacey Rucas – Allies and Rivals: The Complex world of women’s social dynamics among the Tsimane of Bolivia

Stacey Rucas: California Polytechnic State University Department of Social SciencesThis research examines the complexity of women's social behaviors with other women through various modes of evolutionary inquiry and methods. Results indicate that women engage in alternating forms of competitive and cooperative behaviors across the lifecourse in their quest for reproductively limiting resources. Data presented will […]

Alison Gopnik – Causal maps and Bayes nets: Causal inference and theory formation in children, scientists and computers

Alison Gopnik: UC Berkeley Department of PsychologyHow do we accurately infer the causal structure of the world around us? Thirty years of developmental research has shown that human children form and revise intuitive theories of everyday physics, biology and psychology. These theories are similar to the formal theories of science. Recent work in philosophy of […]
